    "body_text": "Software workspaces do not hold still while an agent reasons. SWE-Shift creates 120 scenarios across 12 change families and nine intervention positions, pairing an unchanged continuation with one that receives a relevant update from the same saved history and files. All 17 evaluated coding-agent systems performed worse after the shift. The paper reports one model falling from 67.35 percent clean success to 24.79 percent shifted success; tool or session changes and stale evidence produced zero paired success across all systems. These are benchmark results, not forecasts for every repository. They isolate a neglected capability: preserving valid work while refreshing state, evidence and requirements after change.",
